In case you needed yet another reason to lose weight, think of how you sleep at night. The more weight you gain, researchers say, the more likely you’ll develop some kind of sleep disorder.

In the Journal of the American Medical Association, University of Wisconsin scientists reported that a 10 percent weight gain increased by six times the possibility of developing sleep apnea, a condition in which sleeping is disrupted by troubled breathing.

“It’s long been known that obesity has been linked to sleep apnea,” said Paul Peppard, a member of the study team. But he says it’s the first time even moderate weight gain has been shown to affect how we sleep.
